I also notice now that I am scanning again that 48%
of my traffic is ARP traffic coming from my router does that not seem a little
high??
Why would it need to ARP so many times isn't there
an ARP cache in the router to allow it to not request so many times? Right now
just in a 2 min scan there was over 2100 requests?
Thanks

That
will obviously be much better. However, I still would hesitate to allow
my provider complete control over my router. I have quite a few
"Tweaked" routers, we run wccp, cef and a few other things that I need to know
are running correctly. Just my .02, Not being a smart ass or
anything.

Well that is true if I had a Cisco router I
would be able to do that but megapath gave me this cheesy Siemens router and
they did not install any kind of firewall software installed so I cant make
any rules in it or I would have done this long ago. The attack stopped so I
am not to worried anymore.. but you are right with the new managed router
from AT&T I will request certain IP schemes to be blocked..

It is not really your providers problem. If you are an ISP,
you need to know how to manage your router. That is not meant to be
a slam or anything, but if you have traffic coming into your network, you
need to know where it is from and how to manage it.

I don't have ping.exe in there?? I also
tried ICMP I am calling my provider to block both their class C blocks
from ever getting to me. My partner went to go pay them a visit OHH man
I feel sorry for them HE IS PISSED!

On your Win2K box, go to 'Services' and
look for ping.exe.

Well it does not appear to be the mail
linux box as much as it is the dns server win 2000 what's strange is
I can physically unplug the cable from the box and the outgoing
traffic stops yet the incoming is still going??? I unplug the wan
and it goes away..

If you are running an old linux box that you don't have a
root password for, that means it is more than likely out of date
as far as patches go. That means it could possibly be
"Rooted" and that is not a good thing!!! There are alot of
DNS DDOS attachs out there, I would download ethereal and watch
the traffic VERY closely for a couple of
hours.

I have Brilan bandwidth control and
for kicks I put my servers behind it and just yesterday I
noticed that I have a steady 250kbps up and down on my DNS and
my mail server I unplug the Lan connection to my T-1 and the
problem goes away so I know it is not my wireless customers? I
did a sweep and found nor worms on my 2000 machine I do have
Linux 6.4 machine that I don't know root so cant run any kind of
scan but it appears that it is coming from the WWW? how can I
tell what IP or where this is coming from its almost like a
DNS??? things are functioning normal but a little slow since
this is taking some of the bandwidth?? can or would my ISP
(megapath) be able to tell where it is coming
from???
I have a strange feeling the WAR
has started between me and the competition since they threatened
to do something for their 3 customers jumping ship and coming to
me because of their poor service!
I have TCP IP Dump but cant really
see any thing specific to those IP addresses??
